1. Locate the origin to explain

Method 1: Using positive and negative limit photoelectric switches

1.1 Install the negative limit photoelectric switch

Turn on the power switch, press the emergency stop button, install the negative limit photoelectric switch, manually rotate the spindle to the minimum distance of the slide table, loosen the set screw of the inductive wheel mechanism, align the light-transmitting notch of the inductive wheel with the soft‑limit protection trajectory line of the negative limit photoelectric switch, and after the photoelectric switch lights up, tighten the set screw of the inductive wheel mechanism.

1.2 Adjust the positive limit photoelectric switch

Rotate the spindle to the maximum distance between the slide and the carriage, adjust the positive limit photoelectric switch so that it illuminates along the soft‑limit travel path, and then tighten the set screws to secure the switch.

1.3 Return to Origin

Release the emergency stop switch and return to the home position at a slow speed.

Method 2: Using the Origin Photoelectric Switch

2.1 Installation of the Negative Limit and Home Position Photoelectric Switches

Turn on the power switch, press the emergency stop button, lock the negative limit photoelectric switch, and lock the home‑position photoelectric switch. Manually rotate the spindle to the minimum distance of the slide table, loosen the sensor‑wheel mounting screw, turn the sensor wheel so that the light‑transmitting notch aligns with the negative‑limit soft‑limit trajectory until the photoelectric switch lights up, then tighten the sensor‑wheel mounting screw.

2.2 Automatic Home Return

Release the emergency stop switch; the machine will return to the home position at a slow, automatic speed.

2.3 Setting the Soft Positive Limit

Manually jog the slide to its maximum stroke and set the soft limit.

Warning

During machine adjustment, do not allow the slide’s drive-shaft bearing to approach the red‑line zone, as this could damage the pitch‑adjustment module.

2. Precautions

When the slide returns to its home position, the slide guide bearing can only move along the working-angle‑variable lead curve. If the slider‑driven‑shaft bearing exceeds the photoelectric switch’s soft protection zone and enters the warning line, there is a risk of damaging the gear‑shift mechanism.
Variable‑pitch slides differ from linear modules: the slide’s maximum and minimum spacing parameters are pre‑set, and its soft‑limit protection envelope is relatively small. When fixture‑mounting errors result in inaccurate part‑grasping spacing, the only options are to make minor adjustments to the fixture’s position or to use a calibration jig to align the fixture correctly. Motor‑assisted fine‑tuning is limited to motion along the working‑angle trajectory; exceeding the configured maximum rotation angle will damage internal slide components.
The motion trajectory of the slide on the variable‑pitch slide table is shown in Figure 6 and Figure 7, which depict the main spindle development drawing; please examine these figures carefully during machine adjustment or operation.

3. Calculation method for the variable spacing parameters of an equidistant-variable-spacing slide table

Basic Parameters

Maximum spacing: 30 mm, minimum spacing: 10 mm, operating angle: 0°–270°

Pitch variation ratio formula: (Maximum pitch − Minimum pitch) ÷ Working angle

Calculation: (30 - 10) ÷ 270=0.074 mm/°

That is: for every 1° of spindle rotation, the slider spacing changes by 0.074 mm.

Calculation Example

Question:The minimum spacing of 10mm needs to be increased to 20 mm. By how much should the spacing between each pair of sliders be adjusted? What angle must the spindle rotate through?

Calculation steps:

1. Calculate the change in slider spacing: 20mm - 10mm =10mm

2. Calculate the angle by which the spindle needs to rotate: 10mm ÷ 0.074 mm/° =135.13°

Conclusion:When the minimum spacing changes from 10mm to 20 mm, the slider spacing increases by 10 mm, and the spindle must rotate by approximately 135.13 degrees.
